Product Overview
The 63 Series is a sealed non-rebuildable version of the 62 Series. These are most commonly used in coil-over applications on both dirt and asphalt tracks. The twin tube design gives excellent feel and grip across all track conditions, but they really shine when there is a lack of grip. Built as a spec shock that could be used at specific tracks or series, the 63 Series can be used in any late model or modified.

QA1 63 Series large body aluminum shocks are sealed, non-rebuildable versions of the 62 Series. They typically find their greatest use in coilover applications on both dirt and asphalt tracks. The twin tube design provides excellent feel and grip across all track conditions, but really shines where a lack of grip is prevalent. It also helps prevent binding if the outer tube gets dented. The 2 in. O.D. lightweight aluminum body can be intentionally run in any orientation with no change in rate. QA1 63 Series large body aluminum shock absorbers are built for any late model or modified as a spec shock—and could be designated as such for specific tracks/series.
